AUTOMATIC FIRE-EXTINGUISI-IER.

Specification of Letters Patent.

Patented July Mi, 1! $1. 1?

Application filed April 6, 1917. Serial No. 180,282.

To all whom it may concern:

Be it known that I, EUGENE DAUoHnR, a citizen of the United States, residing at lVood'side, in the county of Queens and State of New York, have invented a new and useful Automatic I ireExtinguisher, of

" which the following is a specification.

My present invention is an improvement of the automatic fire extinguisher, for which Letters Patent were granted to me on May 25, 1915, No. 1,140,960, and it consists in the novel features hereinafter described.-

Theobjects of my improvement, in addi-. tion to those expressed in my above patent, are:

First, to improve the operation of my automatic fire extinguisher in general.

Second, to prevent the leakage of the extinguishing fluid between the stationary and moving parts of the apparatus.

Third, to spread out the extinguishing fluid over a-largerarea when in action Fourth, to make the apparatus more simple, durable and inexpensive.

I attain these objects by the device illustrated in the accompanying drawings, in which Figure 1 is a longitudinal section of my automatic fire extinguisher through the axis of the supply pipe, showing the revolving sleeve 15 in the position when the extinguisher is in action.

Fig. 2 is a top view or plan of my automatic fire extinguisher showing the combustible elements 28 in position when the extinguisher is not in action, but ready for emergencies.

Fig. 3 1s a sideelevation of my automatic fire extinguisher showing the revolving sleeve 15 in the position when the extinguisher is not in action, and omitting the deflector-20 and yoke 26.

Similarnumerals refer to similar parts throughout the several views.

10 is the supply pipe for the extinguish sliding fit on said pipe 10, and restrained endwise by said cap 11 and collar 14..

Said sleeve 15 is shown as having a circular opening 15, which is shown in Fig. l as registering with a similar opening 10 in the supply pipe 10 to permit the escape of the extinguishing fluid when the extinguisher is in action; when not in action, the opening 15 is in the position shown in Fig. 3, when the supply pipe 10 has its opening 10 closed by the sleeve 15, which may be made fluid tight either by a snug fit on said supply pipe 10 or by suitable stuffing if desired.

To keep said sleeve 15 in the normal position, as shown in Fig. 3, I provide the spring 22, which is shown in Fig. 2 as connected at one end thereof to said ring 13 and at the other end to the bracket 23; which is shown as secured to said sleeve 15 by means of suitable screws; a similar bracket 24 is secured to said sleeve 15, and a frame 25 attached to the end of said bracket 24; a number of readily combustible elements, such as the strings or cords 28, are fastened each at one end thereof to said frame 25 and at the other end to ring 17, carried by a bar 16 secured tosaid collar 13; the spring 22 is initially strained and tends to rotate said sleeve 15 out of the position shown in Fig. 3, and into the position shown in Fig. 1; the tension of the strings or cords 2S resists this tendency of the spring 22, un til said strings or cords 28 are destroyed by the flame of a conflagration, when said spring is released, and it forthwith turns said sleeve 15 into the position shown'in Fig. 1, thereby allowing the extinguishing fluid to escape from the supply pipe 10 through the openings 10* and 15; the deflector 20 then causes the fluid to be spread out over a large area; said deflector 20 is supported in position by the yoke 26, pivot 19 and head 18.

21 are the vanes formed at the rim of said deflector 20, which vanes are adapted to be acted on by the extinguishing fluid, thereby causing said deflector to rotate, and thereby still further spreading said fluid b virtue of the centrifugal force of the rotation of said deflector 20.

27 are thefianges of said yoke 26, shown in Figs. 1 and 2 as secured to said cap 11 and collar 14 by means of suitable screws.

boxes,

A combustible bag, such as described in my above patent, may be em loyed to cover the frame '25, cords 28 and t e parts of my' fire extinguisher adjacent thereto; also a fuse may be employed, as described in said ring 17, a large radius of action may be secured thereby.

Many changes could be made in the details of my automatic fire extinguisher Within the scope ofmy invention; I do not, therefore, restrict myself to the design of the details as shown in the drawin s; but I intend to include also all mechanical equivalents and obvious modifications of the same.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In an automatic fire extinguisher the combination of a supply pipe for the ex tinguishing fluid, a revolving sleeve on said supply plpe, an opening in said pipe and for bringing said openings into registration with each other and a deflector for the "extinguishing fluid discharged, through said opening.

2. In an automaticfire extin uisher the combination of a suppl pipe or the extinguishing fluid, a revo ving sleeve on said supply pipe, an opening in said pipe and an opening in said sleeve, said openings being adapted to register with each other, a means for keeping said openings outof registration with each other, a means for bringing said openin s into registration With each other, a deflector for the extinguishing fluid discharged from said openings, and'vanes on said deflector, said vanes being adaptedto cause said deflector to be rotated by saidv fluid.

EUGENE DAUCHER.
